The concentrations of 10, 13‐epoxy‐11, 12‐dimethyloctadeca‐10, 12‐dienoic acid (F20) and 12,15‐epoxy‐13, 14‐dimethyleicosa‐12, 14‐dienoic acid (F22) were determined by a stable isotope dilution assay in oils extracted from the soybean cultivar Century and from five soybean genotypes that lacked one or two of the three lipoxygenase isoenzymes. The concentrations of F20 and F22 ranged between 190–225 mg/kg oil and 91–132 mg/kg oil, respectively. The concentration differences were not correlated to the differences in lipoxygenase activities of the soybeans.
